Here is the third member of Pai Sakura’s group, Watanabe Chiaki. She is the counterpart to Yamashita Yumi’s Akimoto Kumiko.
Chiaki is part of the kendo team, and is second only to Endou Mihara (the two have been called the “kendo babes” by some of their classmates). She is quick on her feet and has aspirations to one day join the military (she will often respond to requests with a sharp “Roger that!” and a salute). While she has been known to sleep with both Sakura and Mihara, she is actually dating Joshuya Chikuma and Higashikuni Ai (they both seem cool with sharing her).
